Additional costs: Ground water wells can also be tested for radon, then, if needed, can get a water radon mitigation system installed. Installing a water radon mitigation system runs from $1,000-$4,500, and maintenance runs $0 to $150 annually.
Radon mitigation is any process or system used to reduce radon concentrations in the breathing zones of occupied buildings.The goal of a radon mitigation system is to reduce the indoor radon levels to below the EPA action level of 4 pCi/L.A quality radon reduction (mitigation) system is often able to reduce the annual average radon level to below 2 pCi/L.In general, costs can range from approximately $800-$2500, with the average reduction system costing approximately $1500.he goal of a radon mitigation system is to reduce the indoor radon levels to below the EPA action level of 4 pCi/L.
